ACETYLENE-GAS GENERATOR. I

SPECIFICATION forming part of Letters Patent no. 694,916, dated March 4, 1902.

f Application filed June 25,1900.

To all whom it may concern.-

Be it known that 1, JOHN HARRIS, acitizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Acetylene- Gas Generator, of which the following is a specification.

My invention is an improved acetylene-gas generator.

One object ofmy invention is to provide improved means for automatically feeding water to the carbid as the gas is generated and consumed and to out off the supply of water to the carbid Whenthe gas is not being consumed, hence causing the apparatus to discontinue the generation of the gas.

A further object of myinvention is to provide a novel form of carbid vessel in which the carbid is divided into separate charges, which are successively attacked by the water fed automatically thereto and in which the supply of water to a charge is prevented until the preceding charge hasbeen expended.

A further object of my invention is to provide means for collectingthe water of condensation from the gas as the same passes to the service-pipe.

My invention consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of an acetylene-gasgenerating apparatus embodying my improvements. Fig. 2 is a transverse sectional view of the same, takenonthe line2 2 of Fig. 1; Fig. 3 is a detail perspective view of the feed-water cock and the vertically-movable .rod carried by the gas-bell to automatically operate the cock and control the supply of water to the carbid. Fig. 4 is a detail perspective view of the carbid vessel. Fig. 5 is a detail sectional viewof the feed-water cook.

The water-tank 1 is provided with a false bottom 2 and is formed with a water-chamber 3 in its lower side. I A vertically-disposed standard 4, which is here shown as a pipe, is secured to and extends through central openings in the bottom of the water-tank and in the false bottom 2 thereof by means of nuts 5. The gas hell 6 is provided with a cen- $erial No. 21,523. "on model.)

trally-disposed depending tube 7, which slides on the standard 4, said standard and said tube 7 coacting to form guides to center the bell in the water-tank. her 3, below tank 1, is a seal-chamber 8, from the upper end of which extends a gas-inlet pipe 9, the upper end of which is in the gasone side of the pipe 10, near the lower end thereof, is adapted for the attachment of the service-pipe. A pipe 12 depends from the upper side of the gas-bell and telescopes loosely on a blow-cit pipe 13 and is provided with an opening 14, which when the same is In the water-chamuncovered by the rising of the bell to an abnormal extent permits the excess gas to be discharged through pipes 12 13 to the air outside of the house. l V

On one side of the water-tank is'located the generating vessel 15, which is provided with a cover 16 and means for firmly securing the cover in place, so that no gas can escape from the generating-chamber into the air. A pipe 17 leads from the center of the gas-generating chamber to the seal vessel 8 in the wa terchamber 3, and the downturned innerend of said pipe 17 "is submerged and sealed in the water within the seal-chamber 8.

On one side of" the water-tank 1 is awatersupply tank 18. I A feed-water pipe 19 leads from the bottom of said water-supply tank to a point within the gas-generatingchamber,

where'it is provided with a suitable dischargenozzle 20, and in the said feed-water pipe is a'cock 21, having contracted openings 22', between which is located the hollow turning plug 23, which is provided at one end with a radial arm- 24, which is bifurcated to form an open slot 25.

A bracket-arm 26 projects from the gas hell, and to-the same is attached the upper end of a vertically-disposed operating-rod 27. The lower portion of the said rod operates in a tubular guide 28, which is secured to one side of the water-tank 1, and the said operating-rod has a vertical slot 29, appropriately ICO located, through which slot the arm 2t extends, and the open slot 25 of said arm is engaged by a transversely-disposed pin 30 in the operating-rod, as shown in Fig. 3. From the foregoing description and by reference to the drawings it will be understood that as the bell rises and descends the plug 23 is turned automatically, and hence controls the supply of water to the gas-generating chamber, the water -supply being cut off automatically when the bell ascends and reestablished upon the descent of the bell, and hence the generation of the gas is automatically controlled, the gas is generated only when the same is being used, and when the gas is not being used the consequent rise of the bell cuts ofi the supply of water to the generating-chamher, and the generation of gas therein is discontinued. When the bell rises to such an extent as to cause the pin 30 to clear the slot 25 of arm 24 and the slot 29 of the operatingrod to clear said bifurcated arm the watersupply is entirely out off from the gas-generating chamber by the cook 21, and one fork of the arm 24 bears against one side of said operating-rod, while the latter may continue to ascend, thereby locking the cock in a closed position, as will be understood. Upon the descent of the bell and the operating-rod the arm 24 by gravity reenters the lower por-. tion of slot 29, the pin 30 reengages the slot 25 of arm 24, and a continued descent of the bell and operating-rod causes the cock to be reopened and the supply of water to the gasgenerating chamber to be renewed.

The pin 30 moves outward in the slot in the forked arm,and the proportions of the slot 29 and forked arm 24. are such that when the gas-bell is in its lowermost position the pin 30 continues to be engaged by the forks of the arm, and hence the cock 31 is locked in its fully-opened position.

The carbid vessel 31, which is placed in the generating-chamber and is provided with a bail or handle 32,whereby it may be readily removed therefrom and carried about, is circular in form, fits snugly within the generating-chamber, and is provided with a series of radial pockets 33. Each of the pockets is of the capacity to contain a charge of carbid, and the partition-plates 34, which separate the said radial pockets, are cut away on their upper sides on reentrant angles, as at 35.

The carbid charges in the various pockets are brought successively into action as the same are attacked by the water. As the water attacks the carbid in one of the pockets the carbid during the generation of the gas thereby swells and rises above the level of the lowestpoints of the upper edges of the partition-plates, thereby preventing the escape of the water into the next adjoining pocket until it has, become entirely slaked, whereupon the water passes from the pocket containing the slaked discharge of carbid into the next pocket in succession containing a charge of active carbid, and so 011 throughout the series, and hence the charges of carbid are successively brought into action and each charge in succession is thoroughly slaked before the water attacks the charge which is next in the series. Hence the gas-generating apparatus requires but little attention to keep the same in operation.

When the gasgenerating apparatus is in operation, the gas passes from the generatingchamber through the pipe 17 into thesealchamber 8, which communicates with the water-chamber 3, bubbles up through the water in the seal-chamber, being thereby washed and purified, passes through the pipe 9 into the bell, and passes from the bell through the pipe 10 to the service-pipe. The water which becomes condensed from the gas passes through the lower submerged end of the pipe 10 into the water-chamber 3. The water in the latter is maintained at a proper level by an overflow-pipe 36.

Having thus described my invention, I claim 7 1. In an acetylene-gas generator, the combination of a feed-water pipe, a cock therein 7 having a forked arm, and a vertically-movable rod, carried by the gas-bell and having a vertical slot to receive said forked arm and a pin to engage said forked arm, substantially as described 2. In an acetylene-gas apparatus, a gasometer or holder, a gas-generator adjacent-to said holder, pipes connecting said generator with said holder, a water-supply pipe leading to said generator and provided with a valve, a bar secured vertically to the drum or cover of the holder and movable vertically therewith, and provided with vertical slots, and a fork connected with the stem of said valve, the prongs or arms of which are adapted to slide in said slots in said bar and to be locked against downward movement thereby when said bar is elevated, substantially as shown and described.

3. In an acetylene-gas apparatus, a watertank, a gas-holder placed in said tank, and comprising a vertically movable drum or cover, a generator adjacent to said holder, pipes leading from said generator to said holder, a water-supply pipe leading to said generator, and provided with a valve, a bar secured vertically to the holder and movable vertically therewith, and provided with vertical slots, and a fork connected with the stem of said valve, the prongs or arms of which cally movable therewith, and a fork connected named tank, a pipe leading therefrom to said generator, and provided with a valve, a fork connected with the stem of said valve, a vertical bar connected with the holder and movable vertically therewith, and provided with' a guide for the arms or prongs of said 'fork, s
